Do you think there was like, a guy and a girl. that figured that they where going to die there, and just like had sex while the gas came in, so they like, the last thing they did was the best thing they did? that would be awesome.

Nope, all in the same room. The goal of the extermination camps was to kill people at a maximal efficiency, sorting men from women would be too inefficient, they only had to go in the "shower room" to be killed afterall.

I think so but when you think about it why? I mean they all die regardless of how they are sorted. Then again maybe since they tried to convince them that it is just an ordinary shower they did separate males and females.
